Williamson: Globalization, Convergence and History

Williamson, JG. 1996. Globalization, convergence, and history. Journal of Economic History: 277-306.

From 1850 to the present, the author highlights three main stages of global growth from the perspective of convergence. "Thus history offers an unambiguous positive correlation between globalization and convergence. When the pre-World War I years are examined in detail, the correlation turns out to be causal: globalization played the critical role in contributing to convergence" (from abstract; 277).

What is the meaning of convergence? "The critical bottom line for me is whether the living standard gap between rich and poor countries falls over time. Convergence implies an erosion in this gap, at least in percentage terms. New growth theorists call this sigma-convergence. To get sigma-convergence poor countries must grow faster than rich, an event new growth theorists call beta-convergence" (279).
